blood project

Blood is a very important part of our body that is why I choose this topic, because I wanted to learn more about how the blood works inside our body. It helps us breathe, and carries nutrients. It helps our body fight the germs that get us sick. Also, it helps us to get rid of the stuff that can not be used in our body.

One very important job that blood has is helping us breathe. Blood carries the air you breathe to every part of your body. The really red blood (which is the type of blood we usually think of when somebody mentions the word blood), is the blood that carries oxygen. The other type of blood is a bluish red, and does not carry oxygen.

Another job blood has is to carry nutrients around your body. Every time you eat, and the food you eat is processed, it’s divided into two categories. One of those categories is the entire good stuff that your body needs. The other one is considered the waste. The waste is carried down to parts where your body can get rid of it.

Lastly, one of the most important jobs blood has is fighting germs. Germs are tiny living things that can make you sick when they live inside your body. Special cells on your blood called white blood cells, fight these harmful germs, and help to make you well again.

All in all, blood has a very important role in the human body; it brings nutrients to your body, and carries oxygen so you can breathe. The blood also fights harmful germs. I choose to write about blood, because I found it interesting to learn about how it works in our body. With this work I learned cool stuff such as: did you know that if you stretched out all the blood vessels in your body and laid them end to end, they would be long enough to circle Earth three times? Amazing!!!
